Answer:

E

Step-by-step explanation:

Let's say "s" represents the number of steps you still need to take to achieve your goal of at least 12,100 steps. You've already walked 5204 steps, and if we add this to s, we should get a total of <em>at least</em> 12,100 steps:

s + 5204

The words "at least" means that we need to use ≥, so:

s + 5204 ≥ 12,100

The answer is E.

If we were to solve this inequality:

s + 5204 ≥ 12,100

s ≥ 6896

In other words, you still have to take at least 6896 more steps.

Step-by-step explanation:

<u>Step 1:  Find the inequality</u>

So, we need to get more than or equal to 12,100 steps per day.  If we already walked 5204, we need to walk another "s" amount to get more than or equal to 12,100.

<em>We need to have "s" plus the amount of steps already walk which is 5204. </em>

s + 5204  

<em>We need this part of this equation to be greater than or equal to 12,100 </em>

s + 5204 \geq  12100

Answer: Option E

What is the area of the circle?
hodyreva [135]

Diameter = radius x 2

So, the radius is half of the denominator.

10 / 2 = 5

A = pi x r^2

A = pi x 5^2

A =  3 x 25

A = 75 ft^2

Hope this helps!

Radioactive Waste The rate at which radioactive waste is entering the atmosphere at time t is decreasing and is given by Pe^-kt,
Dmitry_Shevchenko [17]

Answer:

\displaystyle{\int^{\infty}_0 {50e^{-0.04t}}\, dt}=1250

Step-by-step explanation:

Given:

T =\displaystyle{\int^{\infty}_0 {Pe^{-kt}} \, dt}

where,

T = total amount of waste

P = 50, the initial rate

k = 0.04

t = time

T =\displaystyle{\int^{\infty}_0 {50e^{-0.04t}} \, dt}

now we need to solve this integral!

T =\displaystyle{50\int^{\infty}_0 {e^{-0.04t}} \, dt}

T = \left|50\left(\dfrac{e^{-0.04t}}{-0.04}\right)\right|^{\infty}_0

T = \left|-1250e^{-0.04t}\right|^{\infty}_0

T = (-1250e^{-0.04(\infty)})-(-1250e^{-0.04(0)})

when any number has a power of negative infinity it is 0. because: a^-{\infty} = \dfrac{1}{a^{\infty}} = \dfrac{1}{\infty} = 0, like something being divided by a very large number!

T = (-1250(0))-(-1250e^0)

T = 1250

this is the total amount of waste
